Heat Stress Information

Operational Alert: Warming Up To Heat Awareness

Heat and humidity create serious health risks for workers. Every year in the U.S., dozens of workers die and thousands more become ill due to hot or humid working conditions. Many of these incidents occur during the first few days of exposure, particularly among new employees, workers returning after time away, or those who are not heat-acclimatized, including workers with underlying health conditions. Regular reminders and early intervention are critical to preventing heat‑related illness.
